镶嵌于基质中硅纳米晶的微观结构及其发光机制研究进展

摘要

Si nanocrystals (Si nc) showed many of the required properties for integrated optoelectronic devices. They have attracted more and more attention and become a hot topic all over the world. The aim of this review is to introduce the progress in the microstructure of Si nc prepared by different methods, and the two different mechanisms for light emission of Si nc. Great progress has been made on the preparation and microstructural characterization of Si nc, but the light emission mechanism is still not clear. It needs further investigation.%硅纳米晶材料显示出许多集成器件所需的性能,已倍受人们的关注,成为国内外研究的热点.本文对利用不同方法制备的硅纳米晶的微观结构进行了综述,并对两种不同的发光机制进行了概述.人们在硅纳米晶的制备和表征方面取得了较大的进展,但对硅纳米晶的发光机制还未完全了解,有待进一步的研究.
